8 1/2 weeks after arthroscopic surgery, pain still persist... doctor laughs!?

about 8 1/2 weeks ago i had arthroscopic surgery to remove the majority of my medial meniscus (had a very nasty large bucket handle tear... and im just 18, sucks!)(doctor/surgeon said he removed the most meniscus from me he has his past 20 some odd years as a surgeon from any other patient of his) anyways i managed to do this when i accidentally popped my knee out of socket in the process of jumping in the air and upon landing all my weight (235lb's) landed on the knee which was OUT OF SOCKET STILL.... yeah very nasty... and very extremely painful, couldn't feel my leg other than an very intense throbbing pain which seemed to echo throughout my whole body for about 4 hours afterwards. SO ANYWAYS i work a very physical job involving moving inflatables (bounce houses and such) around with dolly carts up and down loading ramps into box trucks and trailers... and enjoy it very much! problem is, after working the days job my knee just throbs of pain... like a 7 on a pain scale of 1-10. the problem is my surgeon/doctor claims my knee shouldn't hurt as bad as i claim 8 1/2 weeks post surgery... but my knee honestly says otherwise... he insist on Darvocet and Ultracet but they are not doing much for the pain... they both do about the same as Tylenol, Motrin, and Aspirin... which kinda just "cover" the pain "somewhat"... but its still painful (like hard to walk on)...what do i do, constantly insist i get a higher up pain killer or what? he just laughs at me when i explain the pain i have... and its not funny, should i see another doctor? by the way i have been in physical therapy for about 2 weeks now (which seems to make it more painful) but i know i need to do it.
